Question

我正在尝试安装＆＃39; tesserocr＆＃39;使用命令

在Ubuntu 16.04上运行python 3.5模块

pip3 install tesserocr --user

OR

sudo pip3 install tesserocr

我已经使用：

安装了Tesseract 3.04和Leptonica 1.73

sudo apt-get install tesseract-ocr libtesseract-dev libleptonica-dev

出于某种原因，当我尝试安装＆＃39; tesserocr＆＃39;

时，Cython正在生成编译器错误

daksh@daksh-linux:~/tesser/tesseract$ sudo pip3 install tesserocr
